What I find so amazing is that you're growing all this with what seems to be a pretty small amount of light. 220 Watts over a 180 gallon tank is only 1.2 Wpg; a lot less than many others are using. How do you have your lights set up? What distance from the water and how far apart? How often do you replace the bulbs?
I'm curious because I'm impressed. Very much so.
